In the harsh marine environment, marine adhesives and sealants need to withstand strong UV radiation, humidity, fresh water, and salt water. It is also essential to durably and securely seal add-on components on a ship’s deck and hull, as well as in the interior, as poor workmanship can lead to corrosion, leakage and damage of the GRP (glass-fiber reinforced plastic or polymer) laminate.

At H.B. Fuller, we offer optimal product solutions in ship and boat building. Our complete line of marine adhesives and sealants has been specially developed to fulfill needs during production and to provide long-term stability in the final product in a broad set of applications.

Boat and ship building projects are becoming more and more demanding in terms of architectural and design aspects, but also with regard to technical requirements. To ensure successful application and design, H.B. Fuller provides professional solutions for the boat and shipbuilding industry. H.B. Fuller offers a complete product range from a single source – from the manufacturing of high-quality glasses to sealing below the water line. All materials are matched to each other. With these system solutions, H.B. Fuller ensures the highest level of safety and quality in boats and ships, from small boats to cruise liners.

Deck Bonding and Caulking

Marine decks—whether made from real wood, PVC, or polyurethane—require durable protection against environmental stressors. For wood decks, sealing joints against water intrusion is critical. Our deck caulking products offer exceptional resistance to saltwater, freshwater, and UV exposure, while allowing for permanent movement absorption and easy processing and sanding. Additionally, deck bedding must accommodate volume and thermal changes due to temperature fluctuations. Our flexible yet strong bedding compounds ensure secure flooring performance under these demanding conditions.

Structural Adhesives

Modern yachts and boats made from GRP or aluminum require strong, flexible bonding solutions for high-stress areas like deck-hull connections, stringers, and flying bridge mounts. H.B. Fuller’s marine structural adhesives and sealants reduce weight, noise, and vibration while absorbing shocks and balancing elongation. Unlike traditional fasteners, our adhesives prevent thermal insulation damage and corrosion, enhancing rigidity and reducing panel weight.
Our solutions are used across marine applications—from walls, doors, and decorative panels to interior linings, floor plates, and ceilings. Key bonding and sealing areas include:
• Outside Bonding & Sealing: High UV and weather resistance for exterior attachments
• Interior Bonding: Eliminates mechanical fixings and noise, compatible with all common materials

Window Bonding, Sealing and Glazing

Bonded windows and structural façade systems are increasingly popular in modern boat and ship design, offering architectural freedom and sleek, frameless aesthetics that create a sense of openness. H.B. Fuller provides advanced bonding technologies for both mineral and synthetic glass, including polycarbonate, enabling durable and flexible installations.

Marine windows face intense mechanical stress, torsion, UV exposure, and harsh weather conditions. Our marine glazing solutions—including structural adhesives, weather sealants, secondary sealants, and cast resins—ensure long-lasting performance. These sealants protect against water intrusion, accommodate thermal expansion, and maintain structural integrity, even in space-constrained environments.

Electronics Protection, Encapsulation, Speakers

Our marine electronic adhesive solutions [LA4.1]deliver exceptional performance in bonding critical components across a wide range of marine electronics applications[LA5.1]. These include systems such as sonar, radar, navigation displays, and communication devices, as well as sealing and protecting electronic control units (ECUs) used in vessel automation and monitoring. Whether it's safeguarding sensitive components from harsh marine environments or providing structural bonding at the device level[LA6.1], our adhesives are engineered to meet the demanding requirements of the marine industry.

Sound Dampening

On the HB Fuller website, our marine sound dampening solutions are designed to address Noise, Vibration, and Harshness (NVH) challenges in demanding environments. We offer advanced foil-backed patches and butyl constrained layer patches with aluminum foil, engineered to insulate, seal, and waterproof electrical wire harness joints and grommets. These double-sided patches bond effectively to metal, plastic, and fiberglass surfaces. The aluminum foil backing reflects sound waves, while the butyl layer converts vibrational energy into heat through shear forces induced between the substrate and the constraining layer. Additionally, phase interfaces within the polymer structure disrupt sound wave transmission, enhancing overall acoustic performance. These features make our NVH solutions ideal for improving onboard comfort and reducing noise in marine vessels.

Panel Production

H.B. Fuller provides a strong range of adhesives to produce sandwich panels and decorative panels made from different materials[LA7.1]. Sandwich elements significantly reduce net weight without losing their intrinsic properties. Materials as diverse as wood, metal, plastics or ultramodern composites with a foam or honeycomb core are used in this context.

Below Water Sealing

In the marine industry, bonding and sealing solutions for applications below the waterline are essential to ensure the long-term watertight integrity of the hull. These areas require exceptionally strong and reliable adhesion to withstand constant exposure to moisture and pressure. Typical applications include hardware bedding, fastener sealing, port light sealing, and windshield bedding. Our advanced bonding and sealing products are designed to meet these demanding conditions, offering key benefits such as being odorless, non-yellowing, easy to process, requiring no primer, and curing rapidly. They are compatible with a wide range of materials including wood, SMC, FRP, aluminum, stainless steel, and other composites—making them a versatile and dependable choice for marine construction and maintenance.
